Mein Auto: 2013 X3
Driving 28d vs 28i

I have found a surprisingly nicely equipped low mile CPO 2016 28d. The dealership where it is located is about a 3-hour drive for me so I havenít had a chance to see it or drive it yet. I am replacing a 2013 X3 28i with about 130k miles that Iím starting to worry about how reliable it will continue to be.

I can understand that it 28d will have more torque but wonít rev and create the same HP as the 28i, I am fine with that. What I donít know about is the sound and vibration of the 28d vs 28i. Iím sure the diesel will be a bit louder from outside, though my 28i, though my X3 sounds loud and rattles at idle but is smooth and quiet once driving.

How is the 28d to drive as far as sound and vibration? Any other 28d pointers or opinions are welcome too.

Thanks

Mein Auto: 2013 BMW 535i X drive
I currently drive a 2016 28d and I love it. It is a bit louder than a gas powered engine, but BMW has added extra sound barriers that nullify most of the extra noise. You pretty much only notice the extra noise at idle and initial acceleration. I especially like the fuel mileage. I'm currently averaging between 32 and 33 combined city/highway and on a road trip to East Texas averaged 39.7 mpg. Vibration hasn't been an issue for me as I don't notice any. I don't think you will be disappointed and probably worth the trip for a test drive.

As an X3 diesel owner, I am obviously partial, however, I have driven X3 gas models on several occasions. The diesel sounds from the outside, a bit agricultural, but that noise doesn't transfer inside even a speed. Performance at slow speed is zippy and outstanding - making it a great urban and suburban vehicle with mine getting about 33 mpg in mixed driving. At speed, the tach never moves since it will take quite a large grade before the transmission is required to downshift. At 70 mph, on can cruise at under 2K rpm making the X3 quiet inside. On the other hand, the diesel becomes quite breathless at speeds above 85. For example, we drove the length of I70 in Colorado and some of the mountain grades were quite steep. In that instance, the diesel did the job, but there was not a lot of power to spare. Relative to the diesel, a gas X3 seems sluggish in town driving as its peek torque curve comes on much later. Moreover, its interior noise is not much different, since its engine runs faster at the same given speed. We do a lot of distance driving, so our 28d provides decent fuel economy and great range. So far, I've not been sorry for the choice. I recall someone here in the East, complaining that diesel was not sold at every gas station, but on our trips out West it's seems to be sold everywhere, so that should not affect you. Unless you've recently driven a modern turbo diesel (from any manufacturer), I think you'll be pleasantly surprised by the 28d.

Thank you for the input. I think this will work for me, i put a refundable deposit on it so that dealer would hold it for me until i could look at it. I know that may not be the best negotiating strategy but this X3 is kind of a unicorn. A diesel with literally every option including M-sport package and dynamic dampers. The dealer is very proud of this car and they say that used BMW diesels are selling fast because their not made anymore. I don't know if i buy that but then again i question everything a car dealer says. I thought used BMW diesels may be a bargain since they didn't sell well new, used they might be even less desirable to the public after BMW discontinued selling them in the US.
